CRUCIBLE OR CASTlNG-LADLE.

SPECIFICATION forming part of Letters Patent No. 308,028, dated November11, 1884.

Applicationfiled July 19, 1884. (No model.) I

To all whom it may concern.-

Be it known that we, JACOB FRIEDRICH ZIMMERMANN and ERNST GEORG ZIMMER-MANN, both citizens of Germany, and residing at Hanan, Germany, haveinvented new and useful Improvements in Crucibles or Casting Ladles, ofwhich the following is a specification.

The object of our invention is to provide a new and improved crucible orcasting-ladle, which is so constructed as to retain the slag and preventits being poured out with the molten metal, &c.

The invention consists of the detailed construction and combination ofparts, substantiall y as hereinafter fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a plan view of our improved Fig. 2 is a crosssectionalelevation of the same on the linear, Fig. 1.

In the embodiment of ouriuvention we place a crucible, D, into acrucible, E, the crucibles being so arranged that the angles of one areopposite the sides of the other. Thus three channels, a a a are formedwhich extend from the bottom of the crucible D to the three corners atthe top of the crucible E. Of these channels two are closed at the topby crucible-lining or other refractory material, so that the moltenmetal can only be poured out of the remaining open channel a. The bottomof the crucible Dis located some distance from the bottom of thecrucible E, and a series of apertures, F, are formed in the bottom ofthe crucible D. The molten mate rial in the bottom of the crucible Eandin the crucible D are poured out through the channel a, whereby theslag, &c., are retained in the crucibles, as all the molten metal isdrawn from the bottom. The molten metal in the crucible D passes throughthe apertureF into the crucible E, and then out through the channel a.

\Ve are aware that, broadly, it is not new to provide a crucible with apouringchannel formed of a partition with its upper end extendedrearwardly crosswise of the crucible.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

The crucible and casting-ladle comprising the outer triangular vessel,E, and the inner triangular vessel, D,with its angles presented towardor crossing the sides of said outer vessel, and having downward-slopingsides, and its apertured bottom disposed above the bottom of the outervessel and inner vessel, hav;

ing an apertured tapered lower end, substantially as and for the purposeset forth.

In testimony whereof we have signed our names to this specification inthe presence of 6 5 two subscribing witnesses.

JACOB FRIEDRICH ZIMMERMANN. ERNST GEORG ZIMMERMANN.
